Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
The Heidelberg Retina Tomograph (HRT) is a scanning laser ophthalmoscope with confocal optics used for macular volumetric quantification. In the cited study, an HRT-based method produced reproducible volumetric measurements of the normal macula.
Usefulness & Problems
Why this is useful
This assay method is useful for obtaining quantitative volumetric measurements at the macula with good reproducibility in normal subjects. The cited work further suggests potential utility for identifying and quantifying diabetic macular oedema and for monitoring responses to argon laser photocoagulation.
Problem solved
The HRT-based method addresses the need for reproducible quantitative assessment of macular volume. It is proposed as a way to support objective detection and follow-up of macular oedema-related changes.

The method uses light input through a scanning laser ophthalmoscope with confocal optical design. The provided evidence does not specify additional practical details such as acquisition parameters, calibration procedures, or subject preparation.
The supplied evidence is limited to a single cited study in normal subjects. Potential applications to diabetic macular oedema and post-photocoagulation monitoring are presented as possible uses rather than independently validated outcomes in the provided evidence.
